GRAPHENE LCD FACTS:

LCD screens have become a common piece of hardware in many households, replacing old cathode-ray tubes in TVs as well as computers. As the screens grow bigger and bigger, the flatness of their component layers becomes more important. An uneven middle layer in an LCD screen often results in “clouding”, also known as the mura effect. A patent application from a Chinese company aims to resolve clouding by using graphene.

University of Manchester scientists, together with collaborators from the Institute for Microelectronics Technology in Chernogolovka, Russia, demonstrate the use of graphene as a transparent conductive coating for photonic devices and show that its high transparency and low resistivity make this two-dimensional crystal ideally suitable for electrodes in liquid crystal devices.

According to the same group of researchers that first fabricated the 2D sheets of carbon nearly four years ago, graphene has the ideal optical properties to form the transparent electrodes in liquid crystal displays (LCDs). The researchers have also developed a technique that overcomes the traditional problems with manufacturing sizable quantities of graphene.

Researchers at the University of Manchester in England used graphene, which is derived from the abundant natural resource graphite, as a transparent conductive coating for electro-optical devices instead of indium, a metal that is becoming increasingly expensive as supplies dwindle. They used the method to make LCDs that contain graphene electrodes, a technology they said could be mass-produced in computers, TVs, mobile phones and other electronic devices within a few years.

Graphene LCD Statistics:

Graphene, a 2D (two dimensional) carbon is a highly versatile material with amazing properties destined to change the way we live and communicate. It is currently the strongest and lightest material known to man. Its ability to conduct heat and electricity is much better than any other known material.Scientists believe that soon graphene will be used commercially on the optoelectronics field, more especially in touch screens, LCDs and in organic lighting diodes (OLEDs).
